lMPRO VEMENT'lN INSECT-gDESTROYING MACHINES.

Specification forming part of Letters Patent No. 193,105, dated July 17,1877; application filed June 21, 1877.

To all whom it may concern:

Be it known that I, KIMBALL O. ATWOOI), of the city, county, andState'of New York, have invented certain Improvements in Machines forDestroying Insects, of which the 7 following is a full, clear, and exactdescription, reference being bad to the accompanying drawings, and theletters of reference marked thereon, making part of this specification,in which.

Figure l is a top plan-view. Fig. 2 is a side view, one wheel beingremoved. Fig. 3 is a sectional view of the stove, hopper, and blower,and the pipe connecting the same.

The object of my invention is the construction of a machine fordestroying insects, such as grubs and worms in general, but is designedto be especially adapted to the extermination of the so-called westernlocust and the potato-bug.

The nature of my invention consists in attaching to the axle of themachine a light stove, and connecting the same with a blower or bellowsby means of a tube. surmounting this tube, and close to the stove, islocated the hopper for the reception of the destroying compound, whilethe lower section of the stove is connected with an escapepipe havingattached thereto a series of flexible tubes, by means of which the fumesof the compoundare carried to the ground. At

l tached by suitable means to the rear of the axle is a horizontal bar,to which is secured the apron or cover designedto prevent the escape ofthe fumes after being delivered by the flexible tubes.

The construction and operation of my invention are as follows:

A is the axle of the machine, and A A lows O is connected with the topof the stove B by means of a pipe, 0, in which is located a valve, 0,for the prevention of back currents. The end of this pipe 0 which entersthe stove is slightly inclined, as shown at c, Fig. 3. D is the hopperfor containing the sulphur, phosphorus,or other suitable substance. Thishopper has an orifice at its bottom, which registers with asuitableorifice in the tube 0, and by this means the sulphur is conveyed to thetube, its flow being regulated by means of the sliding valve d.Connected with the lower section of the stove by means of a short pipeis a horizontal pipe, E, which is secured by suitable means to thebottom of the axle. This pipe E has attached to it a series of shorttubes, e e, to which are secured the flexible tubes E E. F F are barswhich are hinged to the rear of the axle, and extend a distancesufficiently far from the same as not to interfere with the operation ofthe wheels.

To the free ends of these bars is secured a long horizontal bar, G, towhich is attached the apron or cover G. This apron or cover can be madeof any light material suitable for the purpose, preferably of goodsail-canvas or enamel cloth, so that it may be easily wrapped up whenthe machine is not in use. The edges of this apron or cover G areweighted to prevent it from blowing in case of wind, and also to enableit to more readily adjust itself to the uneven surface of the ground. Toone of the bars F is secured a lever-handle, a, one end of which isprovided with a book, 0 By means of this lever-handle a and the chain a,attached to one of the shafts, the apron or cover G is held in anydesired position, being raised or lowered as occasion requires.

The operation is as follows: The sulphur or other insect-destroyingcompound is placed in the hopper D, the valve 01 being set to regulatethe flow of the same into the pipe 0. The stove B having been properlycharged with charcoal or other suitable substance, the same is lighted,and the blower or bellows O operated. This forces currents of air intothe stove. The sulphur or other compound, falling on the burningcharcoal or Wood, becomes ignited, and the smoke or fumes thus producedfinds vent into the escape-pipe E,'from which it is carried to theground at the rear of the machine by means of the flexible tubes E E,and confined by means of the apron or cover G.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is-

, 1. The apron or cover G, attached to the rear of an insect-destroyingmachine, to operate substantially as described, as and for the purposespecified.

2. In an insect-destroying machine, the

stove B, pipe 0, blower O, hopper D, pipe E,

flexible tubes E E, and. apron G, the whole constructed and arranged tooperate substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this19th day of
